}

Contains a variant per dispatchable extrinsic that this pallet has.

Variants

claim_handle

Claims a handle for a caller’s MSA (Message Source Account) based on the provided payload. This function performs several validations before claiming the handle, including checking the size of the base_handle, ensuring the caller have valid MSA keys, verifying the payload signature, and finally calling the internal do_claim_handle function to claim the handle.

Arguments

• origin - The origin of the caller.
• msa_owner_key - The public key of the MSA owner.
• proof - The multi-signature proof for the payload.
• payload - The payload containing the information needed to claim a new handle.

Errors

This function may return an error as part of DispatchResult if any of the following validations fail:

• Error::InvalidHandleByteLength - The base_handle size exceeds the maximum allowed size.
• Error::InvalidMessageSourceAccount - The caller does not have a valid MessageSourceId.
• Error::InvalidSignature - The payload signature verification fails.

Events

• Event::HandleClaimed

Fields

msa_owner_key: T::AccountId

proof: MultiSignature

payload: ClaimHandlePayload<BlockNumberFor<T>>

retire_handle

Retire a handle for a given DisplayHandle owner.

Arguments

• origin - The origin of the call.

Errors

This function can return the following errors:

• InvalidHandleByteLength - If the length of the payload.display_handle exceeds the maximum allowed size.
• InvalidMessageSourceAccount - If caller of this extrinsic does not have a valid MSA (Message Source Account) ID.

Events

• Event::HandleRetired

change_handle

Changes the handle for a caller’s MSA (Message Source Account) based on the provided payload. This function performs several validations before claiming the handle, including checking the size of the base_handle, ensuring the caller has valid MSA keys, verifying the payload signature, and finally calling the internal do_retire_handle and do_claim_handle functions to retire the current handle and claim the new one.

Arguments

• origin - The origin of the caller.
• msa_owner_key - The public key of the MSA owner.
• proof - The multi-signature proof for the payload.
• payload - The payload containing the information needed to change an existing handle.

Errors

This function may return an error as part of DispatchResult if any of the following validations fail:

• Error::InvalidHandleByteLength - The base_handle size exceeds the maximum allowed size.
• Error::InvalidMessageSourceAccount - The caller does not have a valid MessageSourceId.
• Error::InvalidSignature - The payload signature verification fails.

Events

• Event::HandleRetired
• Event::HandleClaimed

Fields

msa_owner_key: T::AccountId

proof: MultiSignature

payload: ClaimHandlePayload<BlockNumberFor<T>>
